The node counter is amazing! Thanks to it I realized I was quite off in my "count" feeling and therefore refactoring what I have is a huge work. I will put it aside (once again the directories are great!) and I'll start from scratch (testing first in unranked/campaign, sandbox. Other great features).

Also it is great that a sub AI is counted only once. So actually the (real) executable nodes are way more than the counter shows.
